Question

One vegetable warehouse had 210 tons of potatoes, another one had 180 tons. 90 tons of potatoes were delivered to the first and 120 tons to the second warehouse every day. In how many days will the first warehouse have 1.2 times less potatoes than the second warehouse?

Answer 1

6 days

Explanation:

The equation for first warehouse would be:

210 + 90x

The equation for 2nd warehouse would be:

180 + 120x

Where x is he number of days.

In how many days will the first warehouse have 1.2 times less potatoes than the second warehouse?

This means the first warehouse expression TIMES 1.2 would give us 2nd warehouse expression. Equating and solve:

`180+120x=1.2(210+90x)\\180+120x=252+108x\\12x=72\\x=(72)/(12)\\x=6`

So it would require 6 days
